AUTOMOBILE WHEEL HOLDING AND 'rnume DEVICE.

Application filed August 16, 1922. Serial No. 582,159.

- holding and truing devices and has particur lar reference to an apparatus employed for straightening or truing the .fellysof automobile wheels and the metalhc, felly band enclosing the same, simultaneously truing the wheel felly and repositioning the outer ends of the spokes extendin through the felly into the o' enings provided therefor 1n the metallic fe ly band.

The primary object of the invention'resides in the rovision'of an automobile wheel holding an truing device inthe form of'a stand having clamping devices at the head thereofanchoring an automobile wheel on the head of the same with a screw operated clamping block positioned above the warped bent portion of the felly for restorin' the same to its proper positionand true wit th remainin portion of the wheel. a

With ti mafter more fully'described, shown in the accompanying drawing and claimed. 7 v

' Referring more in detail to the accompanying drawing, and particularly toFig. 1 there-is illustrated a device forholding and truing automobile wheels,.the floor plate 1 being mounted upon feet 2 and supporting a centrally positioned standard 3 preferably of rectangular-formation upon the upperl end of which a cross head 4 is supported. For bracing the cross head 4 and preventing warping or; bending thereof, cross bolts 5 extend transversely therethrough as clearly shown in Figs. 1 and 3 and are anchored therein by jamb nuts 6.- Said cross head 4'- is provided with a centrally positioned opening 7 and lateral endopenings 8 as shown in Fig. 3 for purposes presently toappear. is anchored at its lower end to the floor. plate 1, the upper end thereof being threaded as at 9 and extending through the central opening 7 in the cross headl as shown in Fig. 1.

In truing a spoked' wheel by stra'i htening a warp or bend therein, the whee W is positioned above the cross head 4 with the upper threaded end of the shaft 9 extending throu h the wheel hub, the wheel'W being end. openin 8 in'the crow head extending upwardly trough the wheels inwardly ,of

the folly and through the slotted wedgebl'ock 10. A plate arm 12 having an opening 13 in ,one end thereoi is received on the upper threaded end 9 of the shaft 9 for engaging. the adjacent side of-the wheel hub w 'le the-screw bolt 11 extends through either of the openings 14 at'the other end of the plate arm while 'a handle nut l5 is threaded upon the upper ends of thescrew bolt 11 and shaft 9 for holding the plate arm 12 in position. The slotted wedge block 10 may be shifted-to insure the .proper horizontal POSllSlOlliDfthe plate arm- 12 when engaged by the handle nut 15 for anchoring the wheel W rigidly The clamping and bending block"16 shown 16 curved on an d or s5 block 10,

wheel between said clamping block and the adjacent end of the cross head 4 as indicated by dotted-lines inFig. 1; Simultaneously with this movement, i. e., the straightening or truing of the warped or bent portion of the wheel felly, pressure is applied to the metallic rim enclosing the telly which will,

shift the same with the felly and cause the adjacent outer ends of the spokes projecting through the folly to be properly positioned in the rim-sockets therefor. The wheel is then allowed to set a sutiicient-length of time, it being understood that suitable gage devices have been applied thereto for accurately determinin the operation thereof, and when removed from the wheel holding and truing device, said wheel will 'havebeen restored to its original condition properly trued and with the ends of the spokes confined within the sockets provided in the metallic felly band.

While there is herein shown and described the preferred embodiment of the present in- A vention, it is nevertheless to be understood that minor changes may be made in the invention without departing from the spirit and scope thereof as claimed.

What I claim is:-

1. In a wheel holding and truing device, a supporting standard, a cross head carried by the upper end thereof, screw bolts extending upwardly from said cross head, a perpendicular shaft extending upwardly through said cross head and threaded at its upper end, a plate arm extending between one of said screw bolts and the upper end of the threaded shaft, a clamping block associated with the other screw bolt and handle nuts threaded on the screw bolts at the upper end of the threaded shaft.

2. ha wheel holding and truing device, including a supporting stand adapted to have the wheel positioned thereon, means for rigidly anchoring the hub of the wheel and the lower true side of the telly to said supporting stand, an adjustable clamp associated with said supporting stand and the warped side of the wheel 'felly, the wheel anchoring means including a plate arm extending between the wheel hub and unwarped side of the fell'y, and a slotted wedge block interposed between the outer end of said arm and felly.

In testimony whereof I aflia my signature.

GEORGE H. HARTMAN.
